Answer:
18 = 3*3*2
27 = 3*3*3
Step-by-step explanation:
Prime factorization breaks the number down into factors that are prime
18 = 9*2
Since 9 is not prime we need to break it down again
18 = 9*2= 3*3*2
27 = 3*9 = 3*3*3
Answer:
D
Step-by-step explanation:
Cos^2 2x=1/4
Cos 2x =+-1/2
2x=z
Cos z=+-1/2
z1=pi/3
z2=11pi/3
z1 and z2 are possible.
x1=pi/6
x2=11pi/6
Answer:
m ≥ 1229
Step-by-step explanation:
Use m for the number of minutes
30 + 0.05×m ≥ 91.45
0.05*m ≥ 91.45-30
0.05*m ≥ 61.45
m ≥ 1229
